An ice cream factory makes 280 quarts of ice cream in 2 hours. How many

Akimi4 [234]

Answer:

6720 quarts could be made in 48 hours.

The rate per day is 3360

Step-by-step explanation:

280/2 = 140 per hour.

In 24 hours ( a whole day) 24 x 140 = 3,360

In 48 hours (2 days) 3,360 x 2 = 6720 or 48 x 140= 6720
